[Class 100 (ii)] A rotary offset machine of the kind in which both sides of the web 1 are printed simultaneously by means of offset cylinders 2, 3 is constructed with a plate cylinder 5 and inking and damping apparatus mounted in a stationary frame, with eccentric bearings for the cylinders 2, 3, operated to trip the impression by means of segmental gears 7, 8 geared to a common gear 9 operated by lever-andlink mechanism from a throw-off lever 24. The eccentric bearings are so constructed that the bearings for the cylinder 2 gives this cylinder a greater displacement than those of the cylinder 3 for a corresponding adjustment, so that as the cylinder 3 separates from the cylinder 5, the cylinder 2 separates to a similar extent from the cylinder 3. The carriage 12 in which the plate cylinder 4 is mounted is also moved laterally on operation of the lever 24 which operates by lever-and-link mechanism, cam discs 16 engaging rolls 15 on each of the two side frames of the carriage 12. The inking rollers 10 can be displaced simultaneously with the cylinder 4 in known manner. The carriage 12 is locked in operative position by means of wedges 31 which engage between a part 29 of the machine frame and an abutment 28 on the carriage 12. To prevent vertical movement of the carriage 12 a ledge 37 on the carriage engages a projection 38 of the frame in printing position.

Patent GB-939798-A (GB)
Title: Process for the recovery of adipic acid
IPC: C07C51/42
Filed: 1960-05-24
Abstract: Adipic acid formed by the oxidation of adipic acid precursors with molecular oxygen in a solvent is recovered by concurrently cooling and concentrating the reaction mixture containing the adipic acid and separating the resulting substantially pure adipic acid. The solvent is preferably a monocarboxylic aliphatic acid having from 2 to 6 carbon atoms in the molecule.  Conveniently, the cooling and concentration is accomplished by evaporative cooling by introducing the hot reaction mixture into a crystallization zone having a vapour outlet connected to a condenser which is connected to a means for producing a vacuum. The solvent is condensed in the condenser and the inerts are removed via the vacuum means.  The residual mixture in the crystallizer is half the original volume of oxidation mixture and contains substantially pure adipic acid crystals which may be separated by filtration or centrifugation. An example describes the oxidation by air in acetic acid in the presence of copper acetate and manganese acetate of an oil obtained by oxidation of cyclohexane and containing 40% cyclohexanone and 35% cyclohexanol, and the recovery of adipic acid by evaporative cooling in an adiabatic crystallization zone.
